Lathe carriage stops?

Limit switch is like on mills - you attach a block to the side of the table and when it drives into the switch it turns off the motor. Likely an option or a 'make it your self' option.

I never like the hard stop - in friction feed it works just fine - friction slips. In geared drive - break a toot ? stall out the lathe - I doubt the later.

You will find out if you have a shear pin, or a shear gear, sooner or later.

Mine has a shear pin. I'd prefer not to test it.

I machined a stop which uses either a micrometer head or 2" dial indicator, but I only use it with hand feed. Photos in dropbox 2003 retired files, CarrStop....

Depending on the size of your lathe, you can get a little casting to do the job. You machine it yourself to fit your lathe bed. It can be a plain stop, or it can hold a DTI for precise positioning of the xslide.

This company sells castings for a lot of different tools and lathe accessories. I can vouch for the quality of the castings and the instructions that come with them, and the company's excellent service. For the carriage stop, see

Guess I'm spoiled, then.

bottom rod with the two clamp on collars pops the carriage out of drive in either direction.

even has a fine adjust on it, but only on the "towards the headstock" side. I really like having the direction reverse right on the carriage, too. Makes left-hand threading a breeze.

Speaking of threading, does anyone else turn inside threads by running the tool upside down on the far side of the bore, rather than rightside up cutting towards the operator? Probably just me, but I'm more comfortable seeing what I'm doing that way... --Glenn Lyford

Nope, the last time I ran with the tool right side up on the far side with the lathe in reverse. That way, the tool was coming out of the hole instead of going in. This was a 5 tpi thread, so even at slow spindle speed, it moved pretty quick. I reported on it a month or two ago on this newsgroup. Look for broom handle thread.

That's a common trick used by those of us that have worked in commercial shops. Be aware that where you place your compound isn't the same as when threading towards the headstock. You likely understand why.

Right, I reversed it (hand wheel nearer headstock). But since this was an acme thread, only 14-1/2 deg. I wasn't worried about the angle too much, because broom handles are far from perfect anyway. I had to modify the profile by rounding off the crests to mate with the molded or cast handle threads.

Very good, Pete. You'd be amazed how many fail to do so (even guys with experience). It often leads to problems.
